TEMPLATE Filed Nov. 5, 1956 ATTORNEYS United States This inventionrelates to the mounting of members upon hinges and more particularly tothe making of rabbets in which hinges, such as leaf hinges, are placedbefore being screwed in place. I i V The most common method of locatingand making the rabbets for the mounting of hinges is tedious andtimeconsuming. For example, if you desire to mount a door upon a doorjamb, the locations of the hinges are measured by means of a measuringmeans such as a ruler. After the locations of the rabbets aredetermined, their area must then be measured and marked. Then therabbets are formed by cutting out to a desired depth the proper size ofrabbet. The cutting is usually done by means of a chisel.

Each time a new door or gate, or any other type of pivotal member is tobe hinge-mounted, the procedure of measuring, marking, and cutting mustbe repeated.

In accordance with my invention a template is provided whichautomatically locates the position and defines the area of each hingerabbet without requiring any measuring or marking. Each template isdesigned for a particular size hinge mount and a particular size door orother pivotable member. For example, I provide a hinge template which isdesigned for use with a 76-inch door and a 3-inch hinge size. Thetemplate is merely slid over the edge of the door and the hinge leafrabbets automatically located and defined. A router can then be used toform the rabbet. Other sizes of hinges and doors can be formed by theuse of a different size template which has the same structure as thetemplate used in forming the hinge leaf rabbets on the 76-inch door.

One aspect of my new invention contemplates the provision of a platemember which can be used in forming ones own hinge template. A handymanor carpenter need only purchase a plurality of the plates according tothe size of rabbet he desires to make. He can then form a template bytaking a board, such as a plywood board, forming spaced-apart notches inthe board and mounting a plate over each notch. The conventional routerbit protrudes beyond a planar router base an adjustable distance. Thebase face is conventionally used as a rest surface which slides along areference surface or the work being routed. The preferred plate of theinvention provides a bearing surface upon which the router base mayslide. The thickness of the plywood board may be selected to space theplate surface the proper distance from the surface to be rabbeted sothat the router bit may be adjusted conveniently within the adjustablerange of the router. My new invention also contemplates the provision ofa hinge template comprising a board-shaped member with the plate membersalready located in the proper positions. The user need only align theends of the board with the ends of the member in which he desires toform the rabbets. The length of the board-shaped member and thelongitudinal separation of the plates mounted thereon are chosen so thatwhen the board-shaped member is properly located on the member in whichthe rabbets are to be made, such as a door, the spacing of the atear Oice 2 rabbets and e area of the rabbets for aparticungsne door' andbinge are automatically located arid defined, respectively.

My new invention will be better understood by dreading of the followingdetailed description when taken in conjunction with the drawings,inwhich: v v I U Yr Fig. 1 is a plan view showing one of myjnw platemembers mounted on a board-shaped member;

Fig. 2 is a view taken along lines 2-2 of Fig. l';

Fig. 3 is a plan view showing my new template for use informing threehinge rabbets; and I V I p Fig. 4 is apcrspcctive view showingthe'loca'tion or new template upon a door edge when the" template isbeingused. i i I 1 V Referring more particularly to Figs. 1 and}, aplate member 10' is shown mounted upon a boardshaped member 12. Theplate member 10' is of a rectangular shape and has formed therein arectangular hole14 Plate 1 0 be mounted upon the board 12 by anysuitable means such as the screws 16.

The side edges 17 and 18 of plate 10 are flanged to fit over the edge ofthe board-shaped member 12. A shorter second flange 19 is providedadjacent flange 17 and parallel thereto to provide strength and supportto the template when construction of the template is completed. Secondflange 19 also provides a guide surface for the router shaft collar anddefines the width limit of the rabbet.

A pair of guide tabs 20 (see Figs. 2 and 4) are formed on the plate 10.These guide tabs are integrally connected to each of the short edges ofthe rectangular hole 14. Guide tabs 20 are disposed perpendicularly tothe plate and have their edges 22 forming stop surfaces parallel to theflanges 17 and 18. Guide tabs 20 extend below the board 12 and the sideedges 22 are located so that the rectangular hole in the plate 10 willautomatically expose an area equal to the desired rabbet size whenplaced upon the member in which the hinge rabbets are to be made so thatthe stop surface registers against the surface of the member normal tothe surface in which the rabbet is to be formed.

The plate members 10 can be used to construct a hinge template forlocating and defining any number of hinge rabbets. The template itselfis constructed by forming notches in a board-shaped member such as apiece of plywood. The length of the board-shaped member 12 is made equalto the length of the door or member in which the rabbets are to beformed. The spacing between each of the plates 10 and the distance ofthe end plates from the longitudinal edges of the board-shaped member ismade equal to the desired spacing of the hinges.

Fig. 3 shows a plan view of a completed template. This template may beof any dimension depending upon the size of the hinges to be mounted andthe size of the door. For example, if a 3-inch hinge size is desired, ahalf-inch plywood, 3%; inches wide and 76 inches long, can be utilized.The distance of the center of the two end notches is 8 /2 inches fromthe longitudinal edges 21 of the board 12. The center notch is locatedat the center of the board 12.

Fig. 4 illustrates the manner in which my new template is used inpreparation for the forming of the hinge leaf rabbets. The template isslid over the edge of the member in which the rabbets are to be formed,such as a door 49. The longitudinal extremities of the board-shapedmember 12 are made to coincide with the longitudinal extremities of theedge of the door 40. The sliding movement of the board-shaped member 12is limited by the guide tabs 20, the edges 22 of which contact the door4 3. The electric router or other cutting means is then placed into therectangular holes 14 and the proper size rabbet is formed. The rabbetsin the door jarnb are made in a similar 'manner. The door is thenmounted on the fly locates the position and automatically defines thearea of the rabbets to be formed. a 1 V n r r I claim! 7 V A templatefor use in forming hinge rabbets in doors and doorway elements by meansof a router and router bit and comprising an elongate member-havinga'length substantially equal to the height of the doorway and havingnotches extending for a portion of the width of the member and spacedalong a longitudinalside of the'memher, at intervals coinciding with thedesired hinge locations on the particular door and doorway element, aplurality'of router guide plates adapted tobe fixed to the elongatemember one at eachnotch, a first and a second guide tab each extendingfrom the central portion 'of each guide plate so "as toiextend throughand beyond 2 the respective notch 'in the elongate'member, the tabsbeing spacedapart a distance greater than the desired rabbet length andextending for a portion of the width of the notch, a router guide railextending from each guide plate near one of its longitudinal edges so asto penetrate a portion of the respective notch depth, the first and thesecond tabs and the guide rail defining in part an opena ing in theguide plate giving access to the area of the door and doorway element tobe rabbeted, a stop on each guide tab adapted to register against asurface of the doorway elements and door that is normal to the surfaceto be rabbeted for orienting the opening in the guide plate 10 withrespect to the area to be rabbeted, a first and a second flangeextending from opposite longitudinal sides of each guide plate so as toregister each against an opposite side of the elongate member, and meansfixing each guide plate to the elongate member at a notch therein.
